BUTTON OR STUD.

SPECIFICATION forming part of Letters Patent No. 437,273, dated September 30, 1890.

Application iiledApril 9 1890. Serial No. 347,228. (No model.)

To all whom it may concern:

Be it known that l, FRANK E. WILLIAMS, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Buttons or Studs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

My invention relates to improvements in buttons or studs; and itconsists of a stationary post or shank with a bent end, to which is applied a bar or shoe adapted to lock automatically by turning the same in a horizontalplane.

The object of the invention is to provide a secure fastening and retention of the stud when in position in an article to which it is applied, as well as to render the same easy of detachment when desired.

Figure 1 represents a perspective View of a button or stud embodying my invention and showing the bar or shoe in a lockedposition. Fig. 2 represents a similar View of the button or stud reversed. Fig. 3 represents a view of the button or stud,showing the parts detached. Fig. 4 represents a perspective View of a modified form of the bar or shoe.

Similar letters of reference are used to designate corresponding parts in the several views. y

Referring to the drawings, A designates the head of the button or stud of preferred form or construction.

B designates the shank or post, which is stationarily secured to the head andhas a bent end C, provided with a recess D at or about the point of bending. To said bent end C is pivoted a bar or shoe E, which is struck up or swaged at one end to form a Iiush end withA the said bent end C, it being understood that the said bar or shoe E is slightly longer than the bent end O. The said bar or shoe E is pivoted to the end O and turns in a horizontal vplane on the latter.

To insert the stud, the shoe or bar E is turned, as shown in Fig. 2, to elongate the bent port-ion O of the shank and to avoid obstruction. After said insertion the said bar or shoe is turned, as shown in Fig. 1, so that the inner part of the swaged or struck-up portion engages the recess D adjacent to the shank B. In this position the swaged or struck-up end of the bar or shoe E projects beyond the shank B and prevents Withdrawal of the stud, said withdrawal being accomplished by turning the bar or shoe in the position shown in Fig. 2.

The parts of the button or-stud are easily constructed and shaped by dies or analogous devices, and the articulation of said parts is readily accomplished by reason of the simplicity of their structure.

Having thus described my invention, what I claim as new is Y 1. A button or stud having a bent shank with a recess at or near the bend thereof, and a bar or shoe having a projection to engage said recess, substantially as described.

2. A button or stud having a bent shank and a bar or shoe pivoted to said shank and having a projection extending upward iush with the top surface of the bent portion of the shank, substantially as described.

3. A button or stud having a post or shank B, with a-bent end O and a recess D, and a bar or shoe pivoted to said end C and having a projection adapted to engage the recess D and lying iiush with the upper surface of the said end C, substantially as described.

In testimony whereof I affix my signature in presence o f two witnesses. Y
